Find the factors of 24 with their sum = +14. The factors are 12 and 2. +14x will be written as +12x + 2x. 3x 2 + 14x + 8 = 3x 2 + 12x + 2x + 8 = 3x (x + 4) + 2 (x + 4) = (3x + 2) (x + 4) All the steps have occurred in the reverse order to the multiplication given above. Resolve into facto..

. The stage when the reproductive system starts functioning is called puberty. In males, puberty sets in between 13 to 15 years and in females, it sets in by the age of 11 to 13 years. The onset of puberty in females is also marked by a monthly event called menstruation cycle. This involves prepara..

>A system of linear equations is said to be consistent if it has at least are solution, otherwise it is inconsistent. Let A be asquare matrix of order n. Following are the steps to find the inverse of a matrix. Step 1: Find the value of the determinants A. That is, find |A| Step..

Polymers - high molecular mass macro-sized molecules consisting of repeating units of monomers - may be synthetic or natural in origin. Addition polymerization are usually performed on alkenes and their derivatives and proceed through chain growth mechanism involving radicals, cations and anio..

alleles is a phenomenon where more than two alleles occur for a given trait. The inheritance of ABO blood groups is an example for multiple alleles. There are 3 alleles responsible for 4 blood groups A, B, AB and O. The inheritance of ABO blood groups is also an example for co-dominance w..

Then (x 1 , y 1 ) lies on both (i) and (ii). Solving for x 1 and y 1 by the method of cross multiplication, we obtain ..
